在PyCharm调试运行中使用logging.DEBUG

Question

What is a good way to set the logging level for a module in pycharm so that debugging statements will print during a debug session? I am using the native python logging module in python 2.7.

Answer 1

Python logging level can be set inside the Python module, not outside from PyCharm. Your Python application must adjust its own logging level.

• Call logging.getLogger() to get the root logger (topmost in logging hierarchy)

• Set environment variable in your run configuration in PyCharm. Detect this using os.environ.get("MYDEBUgVARNAME") and then call root.setLevel(logging.DEBUG) . I am not sure if PyCharm itself sets any variable based on if it's normal or debug run.

Answer 2

A more straightforward implementation of the previous answer might be to use the DEBUG variable since this is already available to your code...

if __debug__:
logging.basicConfig(level=logging.DEBUG)
